ERC-721 NFT Creator

WHAT IT DOES

ERC-721 NFT Creator lets you deploy a standard ERC-721 non-fungible token collection with just three parameters. You provide the collection name, symbol, and base URI, and the tool prepares, signs, and broadcasts a deployment transaction from your connected wallet. The contract follows the ERC-721 standard, allowing you to mint NFTs with token URIs constructed from the base URI and token ID (baseURI + tokenId). It reads the current network chain ID and gas price from your wallet provider to ensure the transaction is submitted correctly. This is the fastest way to launch a basic NFT collection without writing a single line of Solidity.

HOW TO USE

Connect your wallet using the "Connect" button. Select the target network (Ethereum Mainnet, Sepolia, Polygon, BSC, Arbitrum, Optimism, and testnets are supported). Fill in the collection parameters: name, symbol, and base URI (the metadata endpoint where your NFT metadata is hosted). The review panel shows a preview of the deployment. Click "Deploy NFT collection" — your wallet will prompt you to confirm the transaction. Once mined, the contract address and transaction hash are displayed. You can immediately view your collection on the block explorer and start minting NFTs using the standard mint function.

TECHNICAL MECHANISM

The tool uses a precompiled, minimal ERC-721 bytecode derived from the OpenZeppelin ERC-721 implementation. This bytecode is combined with ABI-encoded constructor arguments (name, symbol, and base URI) to form the complete deployment payload. The transaction is sent via the wallet's signer with a gas limit of 3,000,000, which is sufficient for ERC-721 deployment on all major EVM chains. The tool does not rely on any external API or contract factory — the entire bytecode is embedded and signed locally, so no third-party service handles your deployment data. After the transaction is sent, it waits for the receipt and extracts the contract address from the transaction receipt's contractAddress field. The tool does not verify the contract on block explorers; that step is left to the user.

WHAT IT CANNOT SEE

The generated contract is a basic ERC-721 only. It does not include mint, burn, royalties, staking, or any other custom logic. The tool cannot verify the security or correctness of the deployed contract — you assume full responsibility for the contract's behavior. It cannot deploy on non-EVM chains (e.g., Solana, Bitcoin). Deployment is limited by your wallet's native token balance (to pay gas fees) and the availability of the RPC provider. The tool does not monitor the contract after deployment, nor does it provide a minting interface or metadata storage.

PLEASE NOTE

This tool is for educational and rapid prototyping purposes. Always review the contract code and verify it on a block explorer before using it with real value. Only use on networks you trust. The tool does not persist any data; all state is lost on page reload. EVM chains only.
